Does not seem to be allowing me to compile the server jars any longer (worked yesterday, Jan 11th, but not today), giving me a permission error I'm not sure how to resolve:

sh: applyPatches.sh: Permission denied
Error compiling Spigot. Please check the wiki for FAQs.
If this does not resolve your issue then please pastebin the entire BuildTools.log.txt file when seeking support.
java.lang.RuntimeException: Error running command, return status !=0: [sh, applyPatches.sh]

Any help would be appreciated
